Abstract:On the basis of the dimensionality of Generalized Outcome Expectancies(GOEs)and according to the levels of both optimistic expectancy and pessimistic expectancy,the GOEs of one hundred and eighty five undergraduates were divided into four types including distinct optimism,distinct pessimism,dual tendency and indistinct tendency.In addition,the influence of undergraduates' GOEs on the preference of risky decision-making under business investment situation was also explored.The results indicated that there was a significant interaction among the risk probabilities,the description frames and the GOEs.And under low risk probability and positive frame situation,the undergraduates with dual tendency GOEs showed more significant risk-seeking preference compared to those with other types GOEs.
